7o nil whomj it may concern.-

Be it known that it, Mouais F. tantum, a citizen of the l'nited States, and a resident of Brooklyn, inthe county of Kings and State of New York, have invented certain new and useful Improvements in Pump-Excavators, of which the following is a specitication.

Ny invention relates to that class of excavators where the material is elevated from the `nottom by means of a pump and deposited in a cow.

Ihc object of my invention is to construct a self-leadingscow o.' barge having the luaehinery and all the appliances placed thereon, and so arranged aste secure. the bcstresults by reducing the height of the lift and to retain the matenial'in the seow securely and to discharge it freely when desired, which will be hereinafter more fully explained, reference be.- ingr had. to the aemnnpanying drawings, in whieh- Figure l repriisentsa longitudinal section of the stcru of thescow or barge. Fig. represents plan of samc.` Fig. 3 isa sideelcvatiou ol'thc pockets and valves in section and enlarged. Fig. 4 shows a cross section of Fig. 3. Fig 3 isa plan ofoue ofthe v-alves detached.

'Fig'. tshows a section of flexible suction hose enlarged. Fig. 7 represents a clamping device for securing suctionpipe in section enlarged. Fig. 8 is au end view of same in secL tion on line.r.rof1f`ig. 7. Fig. 9 is a moditication ofthe valve-doors.

A represents the scow or barge, in the stern of which is constructed a well or open-end tank, f t, the sides and end l 2 3 of which are watertight. rihe deck 4 ofthe well is placed a little abovelight water line C. On thedcck 4 in the well ll is placed thepump l) and univel-sal joint l, (which is described in Letters iatent of the tlnited States, No. 332,225, granted to me on the ith day of December, lss5,) to which the suction-pipe lf is attached, and thence extending over aft to the bottom. The well li may becnt outentirely, if desired,

'l`he driving-shaft 5 of the pump passes through the n all 2, and is kept tightby a snitable sluiting-box. ti, the shaft bei-ng there attached tot-hedrivingpanel-,placed inthe comF partment (i surronmling the well or tank l.

Une or more pumps may be placed in the well Patent No. 363,202, dated May 17,1887.

Serial No. ltlfhll, (No modil it desired. Connecting the pump D and the suction-pipe F,iuside of the universaljoint Itis a section of tlcxiblc suctiouhosc,ili, consisting of oneor more conical thi'mblcs,7,which overlap one another freely, and the whole is covered with a ilexible corrugated covering. 8, as shown in Fig. 6, which allowsthe section of hose Il to be twisted and bent in any direction desired freely. The said thimbles 7 are prc vented from being displaced endwise by the inward -protruding lugs 9 on thimbles (l and pins 11, or any other suitable holding device may be employed. The thmbles 7 may be re moved whenclean water is being pumped, as the said thimbles 7 are 'only used to prevent the inner eorrugation from wearing off.

To facilitate the rcmoviugof the tbimbles 7 when desired, one of the thimbles, 10, is made larger than the lai-gc end of said thimblc 7, so that the said thimblc will pass through freely, and they are prevented from going in the opposite direction by the inward-protruding lugtl.

Attached to the suction-pipe 14`instoutside ofthe universal Ijoint E, is a bell-mouth connecting-joint, K, which consists of the conical sleeve 12,(tting on thc conoslecvci, both of which are connected together by the hinge 14, and the said sleeves 12 and 13 are securely clamped together when working by the lugs 15,

which arcseenred to sleeve 12, and passing through tlange 17'ofslcevc12i, where they are caughtby the bevel or wedges a on ring` 16, placed back of the flange 17 and operated by the bevel-pinion 1S and handle 19,'the said ring 16 locking or clamping all the lugs sinmltaueously. The handle J9 extends above the deck of thc scow or barge, so that thejoint l can be connected or disconnected when submerged to thel water-line T1. The object ofsnbmerging the whole appliance is to prevent any airlcaks that may occur, and also to lessen the height ofthe lift of the material from the bottom.

To the lower end of the suction-pipe F is attached the oscillating suetionshoe N, to the after cud of whiclris secured a roller, 25, to prevent the shoe N catching in the material and .breaking the pipe F or its connections if the boat should bc moved backward.

The, nuiterial is discharged into the pockets )I bvthev discharge-'pipe 20. The bottoms of the pockets )l are provided with valves 2l.,

IDD

l 2 y i v seaaoz which are beveled t'o-it from below in correl 5 prevent anyof the material -from leaking ont,

' but are readily opened by loweringsaine when it 4is. desired to discharge theload. The valves 21 may be madesquare, if desired, and hinged A at one side, as'sliown in Fig. 9, and hang down r'ofrom one side, as shown by dotted lines, and

to enable the said valve to be seated` securely the binge 26 is made with an oblong l1ole`,which will overcoiiie any wear there may bc in scat 22. What lclaim, and desire to 'secureby Leti 5 ters Patent, is 1. 1n an excavating scow o barge, A,il1e

deck thereof being jnst above the light water line, substantially as and for tlic purpose 2o Specified.
